How do I go on after trying dungeons hundreds of times?

The standard method is to DF until you know you're not the problem, then PF/shout to increase your average results. If you have an FC or friends that can change the equation, well, that changes the equation. Personally, I just DFed my 2nd and 3rd relic. I feel like I learn my classes better with random knuckleheads, so taking that view helps me deal with the grind.

How you could pull it off, with only one day left, no idea. PF would probably still be your best bet unless you're loaded and want to buy runs or something.

The way I deal with it is to retire from trials. From hundreds of attempts, my experience is that parties have a 100% failure rate on Titan HM, Thornmarch, Ultima's Bane and higher content. The problem is that top tier weapons cannot be bought with tomes and must be won from primals, so I have to use a PvP weapon for PvE content since I have no other options.
